WebAug 10, 2024 · The greater the flow rate, the less time water will have to absorb heat until it exits the pipe, and the colder it will be near the outlet. According to Newton's law of cooling, the heat transfer rate to the water along a given piece of the pipe is proportional to the temperature difference between the hot body and the water. WebMar 5, 2016 · @justinj I agree. The larger volume of the pipe in the middle is likely to have roughly the same effect as making a smaller pipe longer. Either way, you have to push more water volume to get water to the far end, so if you're pushing hot water, you're going to have to push more cold water out of the way to get the hot water to the other end.
